Abstract
An ultrasound sensor includes a transmitting/receiving device configured to transmit/receive ultrasound waves; and a controller configured to make the transmitting/receiving device transmit an ultrasound burst wave, as each of the ultrasound waves, and detect an object through a reception signal that is output from the transmitting/receiving device. The controller is configured to shift operation mode to a detecting mode, when the object is detected in a monitoring mode. In the monitoring mode, the number of waves included in the ultrasound burst wave is changed in two stages. The detecting mode is of detecting the object, using the ultrasound burst wave having the waves that are being used at a time point when the object is detected in the monitoring mode.
